Geology--Illinois--De Kalb County


Geologic and pedologic data and interpretations are provided as an aid to land-use planning in DeKalb Township. The study provides information on local resources and on the suitability of areas for specific uses. The information is presented in descriptive, tabular, cross-section, and map form. The major maps were constructed from field sheets of the United States Soil Conservation Service's Soil Survey of DeKalb County and from well logs. From the information provided, several general conclusions about DeKalb Township were reached: (1) groundwater of good quality can be obtained at some depth everywhere beneath the township, (2) the surficial materials of DeKalb Township are in general not suitable for septic tank filter fields, (3) high water tables present the greatest problem to foundation construction, (4) the soils are unsuitable as road fill material and will present a special problem in street construction, (5) it is not presently economical to mine DeKalb's clay, organic, dolomite, and sand and/or gravel deposits, (6) no recorded earthquakes that have occurred in the northern Illinois region have been of a high intensity.
